Can you explain the concept of the basic model and its role in the system?

The base model is a fundamental class or data structure that describes the core properties and behavior of an entity in a system. It serves as a foundation for creating more complex models and ensures data consistency.

Role of the base model in the system:

• Defines key attributes and methods common to all derived models.
• Provides code reuse and simplifies maintenance.
• Allows building class hierarchies with inheritance.

Example in Python:

class BaseModel:
    def __init__(self, id):
        self.id = id

    def save(self):
        print(f"Saving object with id={self.id}")

class User(BaseModel):
    def __init__(self, id, name):
        super().__init__(id)
        self.name = name

user = User(1, "Ivan")
user.save()  # Saving object with id=1

Here, BaseModel defines a basic structure with a save method, and User extends it by adding specific properties.
